How do I change the font-size of an element within <select>?

Question

I have built this fiddle as an example of what I am doing.

What I am trying to do works fine in Firefox. With the font-size being 14px when you open

Answer 1

.service-small option {
    font-size: 14px;
    padding: 5px;
    background: #5c5c5c;
}

I think it because you used .styled-select in start of the class code.
